Advanced Feature-Set and Industry Leading Performance Enable Scalable, High Performance Radio

Chelmsford, MA 01/31/2013 -

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has launched the HMC835LP6GE, a Wideband Fractional-N PLL with Integrated VCO that generates continuous fractional frequencies between 33 MHz and 4100 MHz. Targeted at cellular infrastructure market, HMC835LP6GE features industry leading PLL & VCO phase noise performance with a PLL Figure of Merit of -230 dBc/Hz in integer mode, and -227 dBc/Hz in fractional mode, and typical VCO phase noise of -134 dBc/Hz at 4 GHz output frequency and 1 MHz offset.

Along with industry leading phase noise performance, the HMC835LP6GE includes advanced features demanded by modern LTE MIMO radio architectures. Two differential or 4 single-ended outputs enable a single HMC835LP6GE to drive multiple MIMO channels. The external VCO input allows the HMC835LP6GE to lock both integrated and external VCOs, and enables cascaded LO architectures for MIMO radio applications. Two separate Charge Pump (CP) outputs enable optimized loop filters, and seamless switching between integrated or external VCOs during operation.

Additional features include configurable output mute function that mutes RF outputs during frequency changes, and Exact Frequency Mode that enables the HMC835LP6GE to generate fractional frequencies with 0 Hz frequency error.Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site at www.hittite.com.
